Yet another Grapefruit update

Today, I updated the Grapefruit FRP library once again. The main improvements are as follows:

  • Grapefruit is now compatible with GHC 8.0.1.

  • The GTK+ UI backend of Grapefruit uses GTK+ 3 now.

The new Grapefruit version is To install or update, you can use the following commands:

cabal update
cabal install grapefruit-ui-gtk grapefruit-examples

As I wrote earlier, Grapefruit 0.1 is actually a phase-out model, which I only update to work with newer GHC and library versions. Starting from March, I will work again on the new Grapefruit, which will be based on my research about FRP semantics. I expect that this new theoretical foundation will lead to a more powerful library with a more sensible interface.
